n Application filed July 80, 1926. Serial No. 125,887.

Our invention is a tufting button for mat tresses, and for upholstery generally, whereby provision is made for the secure attach ment of a button to a loop of a tufting thread.

The object in-view is to attach a button .with facility to 'a thread loop and to retain such button in efi'ective engagement with said loop, said attaching and retainin ping the tongue into engagement with the loop of a tufting thread, said tongue being characterized .by the provision of members extending sidewi'se from the respective edges of the tongue and spaced relatively thereto in order to. leave openings for receiving the two strands of the looped thread.

Other functions and advantages of the invention will appear from the following description taken in connection with the drawings, wherein- Figure 1* is a perspective-view of a mattresswith our button applied to the thread loops thereof. v

Figures 2 and 3 are views in vertical section illustrating'a part of the mattress with our button attached to the thread loop.

Fi ure 4 is an under plan view of the button illustrating the function of the tongue Figure 5 is an edge view of the button back showing the tongue.

, .Figure 6 is an enlarged sectional view of v the button, back and the engagement of the thread loop with the tongue, the section I being takenon the line 66 of Figure 5. 4o

bodied in a buttoncomprising a plurality.

In a practical form, our invention is emofmetal moulds or shells, with orwithout a fabric covering for the front mouldor shell. As shown, the button comprises a front shell or mould A, a back shell'ormould B, and an encasing member, such as a fabric i C for the front shell, the several parts being of the fabric.

The back member B has a tongue D of I assembled and united for the marginal edges of the two shellsto be interlocked with each other and. to confine and grip the edge part novel formation, said tongue being struck up from the metal comprising the member and affording means whereby the button' as plane of the button back, thus providing for the entry of the thread loop into the space between the button back and the tongue. The wings E extend backwardly, from the end of the tongue and they are spaced relatively'to the side edges of said tongue, thus openings, 6. which-arebounded partly by the-edges of the wings E, and partly bythe edges of the inclined tongue D.

.The tongue and the lateral wings thereof resulting in the formation of notches or prerent an arcuate edge f the length of which is equal to the combined width of the tongue and the distance of the wings from the axial line of said. tongue, said extendedarcuate edge f constituting a prolonged edge "beneath which the thread looppasses, and said. edge functioning as a guide for the entry of the thread loop, whereby the button .is attachable with facility "to the thread loop.

. The tongue and the wings thereof are stamped or struck up from the metal composing the shell or button back B, and in such stamping operation the metal is cut or slitted along defined lines to result in the tongue and the lateral Wings, and in addition thereto, the metal is so slitted or cut as to result in the formation of lips g, g, the latter being due to the notches or spaces e, e, at the respective sides of the tongue D and in rear of the wings E. These lips g, g, are opposite to the notches e, e, and they are desirably deflected at an angle to the inner face of the shell or mould B. By. the formation of the lips opposite to the notches e, e, and the inclination of such lips in an opposite direction to the inclination of the tongue D,- there is 7 ample space for the reception of the strands of the looped thread, thus contributing to the facility of the attachment of the button a to the looped thread.

It may be'desirable to provide a seat on the tongue for the engagement of the thread loop, andwe make such provision by bending or deflecting the tongue D intermediate the wings E and the line at which the tongue joins with the metal of the shell B, said bending of the tongue producing a curved part It functioning as a seat for the reception of the thread loop.

As illustrative ofthe mode of using the Jutton, we have shown it in connection with and the mattress,. and pressure is applied edgewise to the button, as a result of which the tongue .1) slips into the loop and the thread enters the notches e, e, in opposite sides of the tongue D. The wings E, E, and the respective edges of the tongue are in contact with the strands of the thread loop, and the lip: g coact to a certain extent with the tongue and with the wings, and in a manner to retain the. button in the required engagement with the thread. The button is thus attached with facility to the thread loop, and the peculiar formation of the tongue and of the wings act to retain the button in the required secure engagement with the thread loop, all of such'attachingand retaining means being unitary with the button. The tongue, the wings, and the lips are formed as arts of the shell B within the marginal e ges thereof, thus producing ma simple economical structure a self-attaching element which is of such relation to the shell B that the latter may be united as usual with the shell A and the fabric cover C.

Having thus fully described the invention, what we claim as new and desire to secure by-Letters Patent is:

1. In tufting button, a tongue provided with wings extending sidewise from the tongue and forming therewith a plurality of thread-loop receiving notches.

2. A tufting button provided on the back thereof with an integral tongue inclined to the plane of said back, and a plurality of wings extending from the side edges of the tongue and forming therewith a plurality of notches at the respective sides of the tongue.

3. A tufting button provided on the back thereof with an integral tongue in offstanding relation to the back, and a plurality of wings extending from the respective side edges of the tongue, the free end of the tongue and the wings being of arcuate formation.

4. In a tufting button, a back shell or mould providedwith a tongue and with a plurality of wings extending from the tongue and spaced relatively to the side edges thereof to produce a plurality of notches, said tongue and the wings being struck up from the metal of the back shell or mould.

5. In a tufting button, a back shell or mould provided with a struck hp tongue and with a plurality of wings integral with the tongue and spaced relatively to the side edges thereof to produce a plurality of notches, and lips integral with the back shell or mould and positioned, opposite to the notches. a

In testimony 'whereof I we have hereto signed our names this 22- day of July, 1926.
